CELL THEORY

upcoming test @____@ I HAVE TO REMEMBER LIKE 8 PAGES OF NOTES SRSLY IM FUCKED -.-

Cell theory
 - cells are the basic units of life
 - cells arise from pre - existing cells
 - all life forms are made up of cells (excluding virii, etc)

Contributors of the Cell theory
 - Robert Hooke (designed a compound microscope to observe cork cells, first person to use the word 'cell'
 - Anton van Leeuwenhoek (discovered uni - cellular[single; one] organisms)
 -
 -
 -
 -

Organelles and their functions
 - Mitochondria (site of aerobic respiration)
 - Nucleus (controls cell activities)
 - Nucleolus (manufactures protein
 - Chloroplast (site of photosynthesis[?])
 - Golgi body (?)
 - Cell wall (?)
 - Cell membrane (?)
 - etc.

Organelles you can see through a light microscope:
 - Cell wall
 - Cell membrane
 - Nucleus
 - Vacuole
 - Chloroplast
 - Cytoplasm

Organelles you can see through an electron microscope:
 - Golgi body
 - Nucleolus
 - Endoplasmic reticulum (S + R)
 - Mitochondria
 - Ribosomes
 - Lysosomes

biology is a bullshit science, go do something worthwhile like physics or chem, kthx.
